DISINFECTING DEVICE.

To all whom it may concern: q

Be itknown that I, THOMAS V. MAnIoeN, a citizen of the UnitedS't-ates,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Disinfecting Devices;and I do declare the followingtto be a full, clear, and exactdescription of the invention, such as will. enable others skilled in theart to which. it appertains to make and use the same.

My invention relates broadly to improvements in disinfecting devices,and more particularly to such an article so constructed as to allow itto be applied as a cover to a garbage can or to analogous forms ofrefuse containers. A

The object of theinvention is to provide 7 a device of this characterwhich may be very;-

simply and inexpensively constructed and marketed, yet one which willeffectively disinfect the contents of the container to which it isapplied, thus destroying any obnoxious odors which might. otherwiseexude therefrom.

WVith this object in view, the" invention resides'in certain novelfeatures of construction and combination hereinafter more fullydescribed and claimed, and shownin the drawings wherein:

Figure 1 is a side elevation of a garbage can showing the application ofthe invention thereto; Fig. 2 is an enlarged vertical section throughthe cover of the arbage can, but showing the means for discharging thedisinfecting fluid, in elevation; Fig. 3 is a similar view of the partsseen in Fig. 2 and illustrating the delivery tube in elevation, with thecap thereon in section; Fig. 4 is a view identical with Fig. 3 with theexception that both the delivery tube and cap are shown in section, andFig. 5 is a detail horizontal section as seen along the plate of theline 55 of Fig. 2.

In this drawing, constituting a part of the application, C designates agarbage pail or can which is shown as provided with the usual archedhandle H. Constituting the cover of the can 0, is a device 1 whereinresides the gist of the present invention.

The device 1 comprises a top plate 2 which may be corrugated as shown inthe drawing or may be of any desired configuration, the edgeof saidplate being provided with a depending annular flange 3 which may fitaround the top of the can G as shown in Specification of Letters Patent.Patented Feb. 15,1916.v Application filed February a, 1915. Seria'1 No,6, 8 19.

the drawing, or maybe received in said top, provided necessaryalterations are made. Spaced an appropriate distance below the topplate2, and secured at its edge within the flange 3, is a bottom plate4, said flange, the plate 4,.a-nd the top platel constituting areceptacle adapted tocontain a; dis

infecting fluid, such receptacle being provided with an inlet normallyclosed by a from the spirit or sacrificing any of the ad-.

vantages of theinvention.

v 'Depending from a central opening in the bottom plate, is a deliveryor discharge tube 10, the upper end of this tube being disposed asuitable distance above said bottom plate, while the lower end of saidtube is provided with a plurality of upright slits 11 and with externalscrew threads 12. En-

gaged with the threads 12, are similar screw threads which are formedinternally of a perforated cap member 13, the curve and threaded wall ofthiscap gradually decreas ing in diameter from its upper to its lowerend as most clearly disclosed in Figs. 3 and 4, this provision beingmade for a reason to be hereinafter more clearly described. In thepresent case, the tube is shown as pro vided with a collar 14 which maybe soldered, brazed, or otherwise secured to the bottom plate 4 asindicated in the drawing. Housed within the tube 10, is an absorbentdelivery member 20 whose lower end pref:

erably terminates about flush with the lower end of said tube, while itsupper end is. curved downwardly as seen at 21 to allow it to depend intothe body of disinfecting fluid 22 which is trapped-in the reservoirbefore described. By this construction, such disinfecting fluid is drawnby capillaryattraction through the absorbent member 20 and is allowed todrip from the lower end thereof through the perforated vcap member 13.The amount of such fluid allowed to be discharged, may now beeffectively regulated by rotation of said cap member in the properdirection. Needless to say, if the flow is too rapid, the cap member istightened upon the lower end of the tube, thereby contracting such lowerend and compress ing the delivery member 20, thus checking the supply offluid. On the other hand, if it is desired to have liquid dischargedmore rapidly, the cap member may be loosened with an opposite result.Regardless of the manner in which. the cap member 1s turned, however, itis effectively held in adjusted position by a spring which depends fromthe collar 14 and whose lower end is shaped to engage a plurality ofnotches 26 with which an annular bead on the lower end of the cap memberis pro vided.

description and the accompanying drawing,

that the article is comparatively simple, may he therefore inexpensivelymarketed, and that it will be a very efficient device for Copies of thispatent maybe obtained for carrying out the object of'the invention;namely, to disinfectthe contents of refuse containersand to therebydestroy obnoxious odors which may otherwise prevail.

I claim:

A device of the class described comprising a reservoir adapted tocontain a disinfecting fluid, a delivery tube leading outwardl y fromsaid reservoir and having :its outer end provided with a plurality oflongitudinal slits, an. absorbent feed member: housed with said tube andhaving its inner end disposed in the reservoir,and a ,perforated tubecompressing; cap threaded on the outer end of the tube, whereby thedischarge of fluid from said tube-may be varied by compressing the feedmember.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
